This work for the first time describes a centrifugal technique for the production and manipulation of highly monodisperse water droplets (CV of droplet diameter below 2%) immersed in a continuous flow of immiscible oil. Within a given working range, droplet volumes (5–22 nL) and their mutual spacing is governed by the channel geometry and the frequency of rotation. Different regimes of liquid–liquid flows are presented. We also demonstrate capabilities like droplet splitting and sedimentation as well as the production of two colored droplets, thus setting the stage for a novel centrifugal platform for multiphase flows.
